Cables for Richard Gray conditioner

I have 2 Richard Grey 400's linked together. If I plug anything into them, they absolutely ruin the sound. It helps the system when plugged into the same outlet, but NOTHING - not even the turntable should be plugged into these things. They say it takes a LONG time for it to break in. I've had the units for a year, and still nothing can be plugged into them or the sound gets muddy, grainy, and closed up. Use the best power cords you can find - that helps as well. As a matter of fact, use the best power cords you can find on EVERYTHING.

I currently use a RGPC600 w/RGPC for video and RGPC1200 w/Shunyata Anaconda for audio. Both terminate into separate 20amp circuits with Shunyata Venom outlets. I started with the stock PC and then upgraded. For both units, the stock PC is good but an upgraded PC just sweetens the pot.

Your observation apppears to be restricted to your system only.

I have 3 RGPC in paralell with amps and subs plugged in with excellent results.

Incidentially, I am using using an Elrod EPS3 Signature for the main RGPC.

I have a RGPC 400S Mk1 & am using an ESP Essence power to connect to the wall. Only my CDP & TT are connected into the 400S & in my system there doesn't seem to be any damage. FWIW.
